Unfortunately you can't import data from an old /opt/zimbra/ folder to a running server..

[WARNING: ]

If you really can't re-activate the old server in order to migrate the data in it, my suggestion is to follow this steps:

- Setup an identical copy of your server. This means installing the same Zimbra version on the same OS over the same architecture. Remember that it must be a PERFECT copy of your old server in order for this procedure to work, so you must also configure the new server just like the old.

- Once the new server is ready
stop Zimbra with

Code:

su - zimbra -c "zmcontrol stop"

copy the old /opt/zimbra/ folder in the new server with a different name

Code:

e.g. /opt/zimbra.old/

rename the /opt/zimbra/ folder of the new server

Code:

mv /opt/zimbra /opt/zimbra.orig

rename the old folder to /opt/zimbra/

Code:

mv /opt/zimbra.old /opt/zimbra

restart Zimbra and hope it works

Code:

su - zimbra -c "zmcontrol start"

Now just follow one of the many migration guides to move all the data from the "copy" server to the production one.

If you need further help on choosing a migration method, I unfortunately tried a lot of them so feel free to ask
